I build expressive systems that give complex work a public voice

What I do and why

I'm Jason Yergeau, a developer and writer based in Haarlem. For twenty years I have worked in the space between the people who build complicated things and the people who have to understand them. I write the software that holds a body of work together, and I find the language that carries it to an audience.

The same situation turns up wherever I go. A team carries far more than it manages to say: research, half-finished experiments, models, archives, a remark made once in a meeting and never written down. The substance is already there. Expressing it is the part that gets left for later, so the work stays clear to the few who live inside it while only a fraction reaches anyone else.

What I build are expressive systems for that material. I begin with what a team already knows and what it is working toward, then design something that gives all of it a steady public voice. This homepage runs on such a system. The essay at its centre is written by hand. Around it a second layer works quietly on its own, surfacing references, drafting annotations, drawing lines between related threads, widening the field of context around the original text. The voice at the core stays mine. The layer around it deepens the reading without ever talking over it.

What comes out the other side might be a website, a content platform, a run of short video. The form follows the work. The principle under it stays put: a human voice at the centre, and around it a system whose whole purpose is to carry that voice further as the work itself keeps moving.

Some teams need a site, and I design and ship it without ceremony. Others want the harder thing, a way to turn everything they are doing into a public presence that keeps pace with them. I am at home in both, and most at home in the room where the engineers, the writers, and the people who have to sell the work are all trying to describe the same thing. Translating between them is the part I am good at.

If your team's public face is thinner than the work behind it, see what I offer.
